PRINTING-RECORDER FOR CALCULATORS.

Specification of Letters Patent.

Application filed November 12, 1906'. Serial Ni). 343,024.

T at? wiwm t'may concern:

means for controlling a numberof columns to be printed with one impression.

in the drawings, Figurel illustrates a sectional side elevation of a portion of a calculating machine showing the recording mechanism. Figs. 2 and 3 represent details.

1 represents a modified form .of recording mechanism showing the application of my invention thereto. Figs. 5 and (3 repre-' sent details of said modification.

in calculating machines, it is deemed desirable. ir making a record of the results when a particular column is to be recorded with a number greater than nought, that the succeeding sections or columns should be printed with a cipher. To effect this result therefore, recording dcvicesare usually so constructed that whenever thedeviceis operated to imprint a figure greater than nought in any particular column, the mechanism controlling the succeeding columns is released autonmtically. It is sometimes desirable however, to print the figures in sevoral columns simultaneously leaving blank space or spaces between columns. to ellect what in the trade is called a splitting of the printing mechanism. It is the purpose therefore of my invention to effect a means whereby the release of the printing device may be controlled absolutely as to the num ber and position of the columns to-be controlled.

in my invention, I refer particularly to I United States Letters Patent Number 505078 issued to dB-S. Burroughs for recording device for calculators, etc, September 12, 1893, and United States Letters Patent Number 580863 issued to De Kerniea J. T. Hiett, for calculating machine, April 20, 1897, as representing the class of devices to which my invention is especially applicable, and to these t o atents I refer for a complete deof the machines to which my invenis, many particulars of which do adapted.

c te part of my invention, and

which are therefore neither illustrated nor described.- I

Referring first to Figs. Ito 3, 'which illustrate the invention adapted to the Burroughs type of adding machine, A. represents the frame of the calculating machine to which my invention is applied. B. represents the frame-supporting the particularmechanism to which my invention is C. represents a shaft upon which the type levers, hereinafter described, are intended to rock. .1). represents-the platen and E. the sheet ofpaper upon which the impression of the type is to be made.

1. represents the keyboard and 2, 2, 2 represents keys operating the calculating mechanism not herein shown nor described. 1. represents the type carrier and 5. a lever arm integral with said type carrier by which the same is operated. 6. represents the type blocks slidingly attached to the type carrier 1, 7. represents the hammer designed to drive the blocks (l against the platen B for the purpose of effecting an impression. Of 9 these type carriers 4, and hammers 7 ,there are as many as there are columns, determined by the calculating power of the machine. They are arranged side by side upon common shafts and bearings. Hammer 7 is engaged withshaft 8 upon which it is intended to rock. It is fitted atits lower rear side with an elongated slot 9. A bell crank lever 10. rocks upon the rod 11 as a fulcrum, and carries near its upper end a stud 12 which engages the slot 9 of the hammer 7. The hammer is driven rearward against the type bloek (3 by the rearward movement of the lever actuated by the spring 14 attached to the forward end of the lever 10. As a means of holding the lever 7 in a retracted position, a; trigger 16 rotating upon the rod 17 is arranged fitted with a notch intended to engage the pointed rearward end 13 of the lever lO, and-hold the said lever and hannner in a retracted position. V

A pawl fitted upon a rod 33 is intendei to engage the trigger 16, and in operation towvithdraw the trigger 16 from its engagement with the lever 10, thereby releasing the said lever and the hammer 7 for the rearward movement. The pawl 15 is arms 31 are rocked upon the shaft 32, the 'pawls 15 are moved forward, and such of them as remam in contact with the triggers 16 draw them forward around the rod 17 and release the levers 10, as before described. Upon the front lower portion of the triggers 16, are rear shoulders 19. I hinge at 21 on said trigger 16, the dog cup or coupler '20 which is fitted on one side with the stud 22 so positioned as to engage the shoulder 19 of the trigger lying next to the one to which it is attached, (1., the trigger neXt leftward as the machine is viewed from the front.

In Fig. 2, the stud 22 which is illustrated, is attached to the trigger which lies in front of the one there shown, and is shown in this illustration in a detached form solely to illustrate its position relative to the shoulder pawl 25, pivoted on a rod 26, and engaged at its rear end 28, with a key-stem 27. This key-stem extends through slots in key-board 1, and is notched in two or more phmes at 3, 3 which notches are intended to engage under the key-board. A spring 28, is lattached to the bracket 30, fitted .pon lthe arm 29, and also to the key-stem 27 to normally uphold the latter. In operation when the dog 20 rests in its normal position, as shown in Fig. 2, the actuation of any trigger 16, will automatically trip all of the succeeding triggers, i. 0., all triggers to gthc right as the machine is viewed from lthe front. This succession maybe broken at will by thrusting downward a keystem 27, which movement engages the pawl 25 with the dog 20 and swings the dog upward upon its hinge 21 and out of contact with the shoulder 19, thereby uncoupling that particular trigger from the one i. 6., next leftward lying next to it.

It is designed that there shall be a keystem for each trigger in the machine.

In Figs. l, 5, and 6, 1 illustrate a modification of my device adapted to the universal type oli adding machine. 7 designates the hammers of this modification jOlllF naled upon theshaft 8 The trigger in this modification is a bell crank lever formed of two arms 16 and 16 journaled upon the rod 17. The arm 16 has a shoulder at its free end to engage with the stud 15 fitted upon the hammer 7. By this engagement, the hammer 7 is held in a retracted position. When released from this engagement, the hammer 7 is driven forward by the action of the spring 14 in order to effect the releaseof the hammer 7", the arm 16 is forced forward by suitable mechanism, which operation moves the trigger arm 1G rearward and free from the stud 15". The trigger arm 16 is held in engagement with the stud 15 by the action of the spring 34: applied to a downwardly projecting arm of the trigger. 19 is a stud projecting from one side face of the trigger arm 18", and is intended to engage with a suitably designed coupler fitted upon the trigger lying adjacent thereto.

Instead of the dog 20, hereinbefore described, in this modification I provide an engaging face 22 which is struck up from a sleeve 20 which is designed to slide up on the trigger arm 16*. A. stud 2% is fitted to the shoulder bearin sleeve 20 and is desi ned 1' 7 l") to engage a slotted pawl or arm 23, which is pivoted on a rod 26, and at its rear end connected to the key-stem 27, which projects above the keyboard 1, and has adjustable engagement therewith by means of the shoulders 3. A spring 28 connects the keystem 27- to the bracket 30.

A representsthe outer casing of the ma chine, and B represents the frame of the' gagement with the stud 1D, and the co-.

operation of all the triggers is ellectcd.

I would not be confined to the partic1 1lar description herein embodied, my intention being to apply my invention to any and all recording devices of whatsoever construction, wherein the automatic relationbe tween each column to be recorded and each succeeding column is desired and utilized.
